Our Stance on AI

We use Agentic AI technology to help us write better code, faster. It is the perfect co-pilot, pairing with our taste and expertise. While it helps us produce the code, we take full ownership of whatever we ship. We have not outsourced our work to machines, nor our judgment.

↳ YEAR 2025

Small Screen,
Big Moments.

Our tenth year was a big one! New RN architecture, Edge to Edge mandatory on Android, Liquid Glass, AI agents, 3D… Phew!

What was once out of style is now trendy again. Skeuomorphic, to flat, and back to skeuomorphic. Snip snap, snip snap!

This year we shipped apps for millions of people, contributed to the React Native core, maintained libraries that power virtually every React Native app in the world, and kept pushing the state of the art.

We helped companies raise Series B rounds, get acquired, hit millions of users, and launch products they're proud of. That's what we're here for.

About

HQ → MTL, CANADA

It all started with a blog in the early days of iOS development. We started pushing the boundaries of iOS before anyone else was doing it. Then React Native happened.

App&Flow was officially founded in 2015 as a Montreal-based mobile app development agency. Later that year, Meta open-sourced React Native, and we were quickly excited by this new technology's potential.

Our early involvement in React Native was noticed by the talented engineers at Expo, who gave us the opportunity to work together on their tools and modules. This collaboration led to opportunities to work with startups coming out of Y Combinator, the best accelerator in the world.

Since then, we have been busy building and helping companies of all sizes with their React Native engineering challenges. Our philosophy changed as well. Give our best to build the best, over-communicate, take ownership, and aim high.

We deliver beautiful apps that work flawlessly, every time. ✌️
